A SUPERCONDUCTIVE UNDULATOR FOR THE MUNICH LASER-PLASMA ACCELERATOR

Laser-plasma accelerators are expected to produce elec- tron beams with bunch charges in the nano-Coulomb range with energies in the GeV range. By employing short- period superconductive undulators (e.g. (1)) this may be utilised for the generation of undulator radiation in the X- ray regime with a compact laboratory-sized set up. In this contribution we report on the project of testing this concept at the Laser Wakefield Accelerator (LWFA) in Munich. A particular aim of this project is to push the superconductive undulator technology to shortest periods and highest on-axis fields at gap widths sufficiently large to reduce the impact of resistive wall wake fields on the electron beam. This might open a path to the generation of coherent radiation via the SASE process.
